Physics 278
Speaker: Reyco Henning, UNC Chapel Hill
ABRACADABRA is a proposed experiment to search for ultralight (10^-14 - 10^-6 eV) axion dark matter, with the ultimate goal of probing the QCD axion at the GUT scale. When ultralight axion dark matter encounters a static magnetic field, it sources an effective electric current that follows the... Read More »

Physics 128
Speaker: Phil Barbeau (Duke Physics)
"The World's Smallest Neutrino Detector" - The coherent elastic scattering of neutrinos off nuclei was first predicted 43 years ago with the realization of the neutral weak current. The predicted cross-section is the largest of any known neutrino interactions; however, the process has remained... Read More »

Speaker: ean-Francois Paquet (Stonybrook University)
The bulk viscosity of a weakly-coupled quark-gluon plasma is expected to be small. On the other hand, for the strongly-coupled quark-gluon plasma produced in heavy ion collisions at the RHIC and the LHC, bulk viscosity could in principle be significant. There are theoretical evidence that the bulk... Read More »

Physics 298
Speaker: Guangyao Chen
We study the exclusive charmonium and bottomonium production in diffractive deep inelastic scattering and ultra-peripheral heavy-ion collisions within the dipole picture. We employ heavy quarkonium light-front wavefunctions inspired by the light-front holographic QCD. The resulting cross sections... Read More »

Physics 130
Speaker: Franco Nori (CEMS, RIKEN)
Recent technological advances have made it possible to implement atomic-physics and quantum-optics experiments on a chip using artificial atoms. These artificial atoms can be made from either semiconductor quantum dots and, more often, from superconducting circuits. Superconducting circuits based... Read More »

Physics 298
Speaker: Huaixiu Zheng (Yale University)
We propose a circuit-QED-based single-microwave-photon detector for dark matter axion searches. The strong coupling between a superconducting qubit and microwave photons makes it possible to detect the extremely weak axion signal with a high sensitivity. With realistic experimental parameters, the... Read More »

Physics 278
Speaker: Mia Liu, Fermilab
The search for supersymmetry (SUSY) is a long-standing important task in particle physics. One prime motivation for weak-scale SUSY is that it protects the Higgs vacuum expectation value without unnatural fine-tuning of the theory parameters. Light stops one of the key features of natural SUSY. In... Read More »
